"The Microsoft Visual Studio Code Remote Windows Subsystem for Linux (WSL) extension is prior to version 0.63.11. It is,
therefore, affected by a remote code execution vulnerability. An unauthenticated, remote attacker can exploit this to
execute arbitrary code on the system with privileges of the victim.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
